• newtons second law of motion

  force= mass x acceleration
• The acceleration of an object as produced by a net force is ( directly, inversely) proportional to the magnitude of the net force, in the (same, opposite) direction as the net force, and (directly, inversely) proportional to the (mass, weight) of the object
• the larger the force applied on an object, the larger its acceleration
• acceleration is defined as the rate of change in velocity with time.
• a vector quantity having magnitude and direction
• In uniformly accelerated motion (uam) the value of the acceleration is constant. it does not change.
• An object with zero acceleration is said to in uniform motion
• Acceleration represents how velocity changes with time velocity represents how position changes with time
• the acceleration due to gravity is 9.8 m/s ² neglecting air resistant
• In general, an uniformly accelerated motion is the one in which the acceleration of a body throughout the motion is uniform.
• trajectory - the arc curve like motion path undergone by a projectile
• projectile - an object undergoing projectile motion
• ange 0 - a numerical value in degrees (°) expressing the orientation of the projectile to be thrown projected
• Horizontal motion x-component

  neglect air resistance

  there is a constant horizontal velocity. Vx

  Horizontal acceleration is 0. ax = 0
• We call the horizontal distance as range.
• range are represented as (dx)
• the force acting upon in this motion is the force of gravity
• gravity represented as (g = ay = ag)
• g = -9.8 m/s²
• vertical velocity is not constant, represented as Vy
• we call the vertical distance as the height
• height is h = dy
• Vx - horizontal velocity responsible for the projectile to travel at a horizontal distance
• Vy - vertical velocity responsible fot he projectile to travel at a veritcal distance
• height - the vertical distance from the projectile to the earth surface
• range - horizontal distance covered by a projectile
